In the French revolution the guillotine became a symbol for the revolution. Today Egypt has been called revolution 2.0 and the symbol of the revolution is Facebook.
The inventor of the guillotine ended up in his own guillotine, apparently his invention was too successful…

There is an interesting connection between the guillotine and Facebook, one of them disconnected faces/heads and the other one connected them but both were successful in getting the revolution through (its all about faces/heads).
